BALL-BEARING.

Specification of Letters Patent. Patented Aug, 15, 1911.

Application filed December 4, 1908. Serial No.465,9.49.

To all who-m it may concern:

Be it known that I, Gnoncn \V. B. McEn- HONE, a citizen of the UnitedStates, and a resident of the city of Binghamton, in the county ofBroome and State of New York, have invented certain new and useful I'm-'provements in Ball-Bearings, of which the following is a specification.

My invention relates to improvements in 1 ball bearings and moreparticularly to revoluble ball bearing rollers or wheels and housingsdesigned for reroluble shafting or spindles.

The object of my invention is the production of a hall bearing roller.wheel or. housing whe-reln adjustment of the races may readily be madeand maintained within the parts comprisin said roller, wheel, or housmg,and the s aft or axle thereof, said means of adjustment thereby beingintegral therewith and not necessarily extending be yond the width ofthe roller, hub of wheel, or housing, thus permitting more compactconstruction of the bearing and the means for securing and maintainingadjustment thereto than is possible in constructions of like characteremploying other means of adjustment now in use; to render the samecapable of being inexpensively constructed andv adapted to be adjustedwith facilityand precision, and capable of being applied where theapplication of ball bearing rollers, wheels, or housings provided withcommon means of adjustment of races would be "prohibitive on account ofthe space inv addition to the width of. said roller, hub of wheel,

or housing their means of adjustment 00- i a gib G-so as to permit saidgib to engage cupies. 7 With 'these'and other objects in View, my 40invention consists of certain novel features of construction andarrangements of parts, all of which will now be *fully described andfinally embraced in the claims. Referring to the drawings, accompanyingand forming'a' part of this specification, in which like letters andnumerals of reference denote the same parts throughout the severalviews: Figure; 1 is an end view of my invention. Fi 2 is a sectionalview, taken on the linen- "of Fig. 1. Fig. 3 is an end View, showing oneof -the cones, the sleeve and the share." Fig. 4 showsthe sleeve andcones, and'whefengaging portion of a gib.

Fig. 5 shows the held withinfthe' sleeve. application Qf my inventionWithin a hub or ournal;"Fi'g'. 6 is a perspective view of a gib. Fig. 7shows my invention used as a cam roller. I

The part A, shown in the various views, is made of suitable material, ineach end of so which are formed the cups B, adapted to, in conjunctionwith cones arranged on a suitable sleeve, form races for balls in theusual manner. Said part A may comprise a case so constructed that thecups B may be fitted therein. The periphery of case A may be the outersurface of a roller of smalldiameter, or one or more of the bearings maybe fitted within a hub, as shown at Fig. 5, provided with any commonmeans for se-' curing spokes or radial arms thereto, Where the bearingis to be used in the construction of rollers or wheels of largerdiameter. The central portion of case A, having contained therein thecups B, is provided with an opening of suflicient size to allow a sleeveD to pass within said part.

The reference letter D indicates'a sleeve of such diameter that, when itis inserted Within the part A, said part A may be rotated 0 around saidsleeve without bearing thereon.

Thesleeve is.ordinarily designed so that it may be mounted upon a shaftor pin I. As shown in Fig. 4, said sleeve is so shaped that cone 0 formsa part thereof, said sleeve and. g5

cone being made of one piece. VVhen the cone C forms. a part of thesleeve, or is fixedly secured thereto, the other end of the sleeve isprovided with screw. threads, in order that the adjustable cone 0 may beso screwed thereupon and thereby be capable of adjustment. A slot P, atthe threaded end of said sleeve, is adapted to contain with an engagingportion provided Within the adjustable cone 0.

When advantage is to be gained by such form of construction, as shown atFig. 2, the sleeve D may be threaded at both ends,

and each cone be adapted to besorewed 10o thereon, in which case bothends of the sleeve D may be slotted, as at P to 'contain.gibs designedto act upon each ofthe adjustable cones for the purpose of maintainingthe adjustmentas hereinbefore described... {The keyway J may beformedwithin'the. sl,eeve,.

if occasion demands it; A keywaytK -in certain forms of construction ofmy device, contains a spring H, or other holding. ,memher, for the gibG, in order to'maintaimsaid 3.10 gib Within the slot P. The adjustable:cone C is adapted to be screwed 'on to the sleeve 1), and is of suchform that a will, in conwith cone 0,. cooperate with the gaging portion:ofgib Gr may be held into engagement therewith and thus preventrotationof said adjustable cone, for the purpose of maintaining the adjustmentofsaid cone and render-the same to be capable of readjustment whenrequired. The races 1 formed by the cups and cones have balls interposedtherein -'in'.the usual manner. The gib G, orsiniilar device, adapted toengage with the grooves F of adjustable cone C is securedito or 'withinthe sleeve, or it may be contained by the shaft or pin I. In the form ofconstruction shown in Figs. 1, 2, 3 and 4:, the gib G is held inposition within the sleeve D by means of the spring H, which spring issecured within a keyway K in said sleeve in such manner that a portionof said gib will engage with the grooves F of the adjustable cone C whenit is required to thus engage them, and further to permit the engagingportion of gib G to become disengaged from'said longitudinal grooves bydeflecting spring H to which'the saidvgib is secured or forms a 0 part.In Figs. 2 and 4;, spring His secured within the sleeve D by means of arivet R. A pin or shaft I, adapted to pass through the sleeve D, isprovided for the purpose nof 'forming a. fastening for the roller or 5Wheel, and the said pin or shaft also serves to securely hold theengaging portion of the gib G into engagement with one of thelongitudinal slots of adjustable cone C and thus prevent rotation ofcone 0, when said 40 pin or shaft is in proper position within saidsleeve. Said pin or shaft may be pro vided with a groove or keyway J, asshown at Figs. 2 and 3, in such manner that a partial revolution orpartial withdrawal of said 5 pin or shaft, or the sleeve mountedthereon, will cause said keyway J to come into such position withrelation to the gib G that the engaging portion of said gib may bethrown out of engagement with the longitudinal grooves Fof adjustablecone C while the said sleeve D is still held on the shaft, and therebypermit adjustmentof cone C without removing said sleeve or the roller orwheel mounted thereon from its pin or shaft, as shown in Fig. 3. Incases where the bearing is to be used in a cam roller or similar device,which may readily be removed for adjustment, said pin I may be of solidmaterial, without the slot J, in which case it will be necessary toremove said pin I in order to allow the gib .to become disengaged fromgrooves F of adjustable cone C to permit its adjustment. Vherever it isnecessary to secure lateral adjustment of 1',ooo.wss

each end of-saidsileeve so that both cones C and C may be screwedthereon, to adapt the sleeve D to be fitted at each end with a gib G, orG and also, to provide both cones O- and C with threads and thelongitudinal grooves F, as previousl and for the purpose shown in thecase of e 1e C Two or more ofthe bearings of like or differentdiameters.

may be insertedi'n an outer shell, thereby distributing the load equallyover a greater area, as shown in Fig. 5.

In constructions wheretwoorhmore units are employed in a bearing,lateral adjustment of the cones of eaclr'umt, in relation to its ballsand cups within the case, may be obtained by so fitting the hole of thesleeve D, adapted to contain the shaft, that said sleeve carrying thecones O and C will be permitted to slide endwise on either a solid orsplined pin or shaft, and thus compensate for unequal wear of either ofthe races or the balls contained therein, whenever it becomes necessaryto change the ad-. justment of the adjustable cone or cones.

In the forms of construction above shown, the cups and case containingthem are adapted to revolve around the sleeve D, cones C and O and thepin or shaft within said sleeve,'but the case A with -its oups'B securedwithin or forminga part thereof may be fixedly secured within a housingor hanger where it is desired to construct'a ball bearing hanger orhousing for revolving shafting, in a similar manneras shown at Fig. 5,in which case the .shafting may be secured within the sleeve and made torevolve. with said sleeve, while the case and the clips containedtherein remain fixed.

In case of my invention being applied to a cam roller orsimilar deviceheld between lugs L and secured by pin I, as shown in Fig. 7 when itbecomes necessary to change the adjustment of adjustable cone or conesto compensate for Wear, said pin I may be withdrawn and the rollerremoved. The gib not nowbeing held into engagement with any of thelongitudinal grooves of adjustablecone by said pin, it may be disengagedtherefrom,*when the said cone may be turned upon the threads of thesleeve in such manner as to secure proper adjustment of the races, afterwhich the gib may again be engaged with a coinciding longitudinalgroove. The roller is then returned to its place and secured by the pinI, which forms its axis, and also serves to hold an engaging portionofthesaid gib into engagement with the coinciding longitudinal slots F ofthe adjustable cone C and prevent the rotation of said cone 0 upon thesleeve D,

Where it is not convenient to remove the bearing in order to makeadjustment, and

where the means for fastening the roller or wheel is simllar to'thatshown Figs. 2

beingprovided with keyways'J, J, as here" inbefore described, after the"key J is withdrawn, the sleeve D may be revolved on said shaft to bringthe gib G into such position that it may be depressed into the keyway Jof the shaft sufficient to allow it to be disengaged from longitudinalgrooves of the adjustable cone C as shown in Fig. 3, when the saidadjustable cone may be rotated upon the threads of the sleeve to makethe adjustment, vafterwhich said sleeve is iven a partial turn upon theshaft or pin,

in order that said shaft or in will hold the maintain the adjustment.

- key J into thekeyway J of the sleeve and the keyway J of theshaft,shown in Flgs.

engaging portion of the gi G into engagenient with the longitudinalslot, and thus By inserting a 1, 2 and 3', the sleeve will be maintainedin a fixed position on the shaft I but the gib G maybe pressed backagainst the action of the spring H and be disengaged from the groove Fof the cone C and thus permit the cone to be rotated for adjustment ofthe races.

Various modifications may be made in the construction of my devicewithout departing from the spirit of my invention.
